Using CUPS on Windows
This is really quite simple.
First click on Start > Printers and Faxes.
This will pop up "Printers and Faxes" menu.
Then click on "Add a printer" link which will pop up the "Add Printer Wizard".
Click on "Next" then "Add network printer, or a printer attached to another computer".
Click on "Connect to a printer on the Internet or on a home or office network"
In the "URL:" text area type "http://machine:631/printers/YourPrinterName" minus the quotes.
If Windows finds your printer it will pop up a screen to let you choose your printer make and type. After choosing this you are done.
